Abstract:
New laser crystals were prepared from potassium-rare-earth tungstates KY(WO4)2 and KGd(WO4)2 activated with Pr3+ ions. Flashlamp pumping at room temperature resulted in low-threshold pulsed and quasi-cw generation of stimulated radiation in the ‘neodymium’ range of wavelengths (1.06 — 1.07 μm, 1D2 → 3F4 lasing channel).
